Signal strengthGeneral

Compared to my Nexus, it's been great judging by the signal strength meter. I'm pulling 4G in places where 3G had been a challenge, and in general the 4G connection seems much more stable. My biggest signal complaint is the phone will hang on to a weak-to-nonexistent wifi connection and try to leach data from it when there's a perfectly good 4G connection available to switch over to. I shouldn't have to manually turn off my wifi to force it to switch.

Signal strength is much better than my Galaxy Nexus. In my office building my GNex pulled in no signal at all of any kind -- voice, data, nothing. My brand new Droid Maxx get at least some 3G most of the time, and in some parts of the building I have a couple bars of 4G.
In fact, that's part of the reason I bought a Motorola phone this time, as appealing as the S4 looked. My GNex melted down irreparably about 2 weeks ago, so I had to pull out my OG Droid until I bought a new phone. I was astonished at how strong the Motorola signal was, how loud the speaker was, and how well the battery performed. Those are pretty important features to me, so I sprung for the Maxx. Three days later, seems like a good choice.
